Hi,
  I expect to have a new test version available soon. The MacOS X Catalina
release has created a lot of extra issues that need to be resolved, so I
may go ahead and make the OptiX updates available this week even if I
don't have all of the MacOS X updates in place yet.

Best regards,
  John Stone
